may also be used to specify a domain name when parameters Primary SIP
proxy and Secondary SIP proxy have been assigned IP-addresses.

• Send DTMF using RFC 2833 or SIP INFO – this parameter defines which
path the DTMF signaling should take. If set to “RFC 2833“, the DTMF
signaling will be sent in the RTP stream, i.e. from handset to handset. If set
to “SIP INFO”, the DTMF signaling will be sent using SIP signaling, i.e. via the
PBX.
• Hold type – defines type of hold to send when the handset puts a call on hold.
The selection depends on what type of hold the PBX support. For more
information about what type of hold the PBX support, see the applicable
documentation for the PBX.
• Registration identity – defines if the endpoint shall use its number or ID for the
registration with the SIP proxy.
• Authentication identity – defines if the endpoint shall use its number or ID for
the authentication with the SIP proxy.
• MOH locally – Music on hold is played by the handset i.e. if the PBX does not
supply MOH the handset plays a tone when the call is on hold.
• Hold on transfer – puts a second call on hold before transfer, which is required
by some SIP proxy servers.
• Direct signaling – defines whether calls originating from other sources than
the configured SIP Proxy should be accepted or redirected using “USE
PROXY“ message.
• SIP Register Expiration - Defines the number of seconds for register
expiration to the PBX.
